four holes on the bottom plate to attach the device to a mounting surface.

Vehicle Mounting

When installing the device in a vehicle:

• Keep it out of direct exposure to the weather (sun, rain, etc.). The best

locations are in places like a car trunk or in a container behind the seats.

• Place it where it will not be hit or come into contact with people, cargo, tools,

equipment, etc.

Antenna Installation

Inadequate antenna separation between the transmit and diversity antennas

creates unwanted interactions. This can cause reductions in:

• Antenna efficiency

• Transmit power

• Receiver sensitivity

• Data throughput

• Radio front-end life span

Antenna Separation Recommendations

• The antennas should be separated so that there is at least 10dB isolation

over the entire operating frequency range.

• The separation should be at least 0.25 wavelength (preferably greater than

0.5 wavelength) of the lowest operating frequency.
